GLUING=WHEEL SPECIFICATION forming part of Letters Patent No. 733,508, dated July 14, 1903.

7 Application filed August 22, 1901. Serial No. 72,885. (No model.)

To all whom it may concern.-

Be it known that I, CHARLIE REDD, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gluing- I'Vheels, of which the following is a specification.

My invention relates to certain improvements in gluing-wheels, such as are used in machines of the class described in my pending application, Serial No. 46,319, filed February 7, 1901, and Serial No. 55,457, filed April 12, 1901.

Among the purposes of the present invention it is desired to provide a gluing-wheel adapted to apply glue to the inside of the end flaps of a carton when said end flaps are of considerable extent, so that if said side faces were integral the difference in velocity of the parts of the inside and outside portions would interfere with the proper distribution of the glue upon the flap. It is also desired to provide positively-rotated pressing devices for crowding the flaps up against the gluingwheel, so that said pressing devices may cause no drag upon the flaps as they pass between.

To such end the invention consists in certain novel characteristics described and claimed below.

The invention is illustrated in the drawings, wherein- Figure 1 is a side elevation of a portion of a gluing-machine. Fig. 2 is a vertical longitudinal section in line 2 2 of Fig. 3 looking in the direction of the arrow 2. Fig. 3 is a vertical transverse section in the line 3 3 of Fig. 1. Fig. at is an elevation of the members of the gluing-wheel, the driving-shaft being cut in the section indicated by the line 4 a of Fig. 3; and Fig. 5 is a plan of one of the pressingrollers in detail, showing the scraper for removing any glue which may accidentally get upon the surface thereof.

Referring to the drawings, A is a part of a suitable framework adapted to guide a series of cartons in succession to the gluing-wheel. By reference to my applications above mentioned it will be seen that this framework is provided with suitable'driving mechanism, a conveyor adapted to receive, hold, and advance the cartons in succession, bringing the a carton.

opposite end flaps thereof in contact with the opposite outside faces of the gluing-wheel, and suitable devices for folding in the flaps, pressing them down one upon another, and holding them there a sufficient length of time to allow the glue to set. It is thought unnecessary to illustrate in the present application any of the parts of the machine, except the gluing-wheel and opposing pressing-wheels, because these are the parts to which alone the present invention pertains.

The framework A, as shown, has two longitudinal members a ct at the top and three guiding members a a a shown as in the shape of a trough at the bottom. Upon the members a a are supported brackets B B, in the upper portions of which are secured sleeves C C, Fi 3, in which are journaled a drivingshaft D, driven by a sprocket d at one end. Upon the middle portion of the shaft are socured against rotation two members E E, making up a gluing-wheel adapted to operate simultaneously upon the opposite end flaps of If one flap alone were to be glued, one member of course would be sufficient. The two members are practically alike and are set upon the shaft with their faces upon opposite sides. Each of the members is provided with a preferably oblique gluing side face e. Upon the inner end of each of the sleeves C C is secured against rotation a pinion o, and adjacent thereto is journaled an inner section F of the gluing-wheel, having a gluing-face f, preferably continuous with and in line with that of the member E. Upon the inside of this inner section is an internal rack or gear f, concentric with the pinion c, and upon the stud G, secured to the said memher, is a loose gear g, meshing both with the pinion c and the internal gearf. The rotation of the shaft rotates the member E, together with the gear g. The pinion c retards the inner side of said gear and to that ex tent increases the velocity of the outer side,

ing wheel a facial velocity substantially equal to that of the outer section. Upon the inner section is secured abevel-gear H in mesh with a bevel-pinion K, fast upon the upper end of a pressing-roller 7c, journaled upon a stud M, secured in a bracket on, fast so as to give to the inner section of the gluto the member a. The bevel-pinion and the bevel-gear are so proportioned as to give a peripheral velocity to the pressing-roller substantially equal to the facial velocity of the gluing-wheel, so that when the carton-flap is brought between the pressing-Wheel and the gluing-wheel the engaging parts will all move with substantially the same velocity.

A scraper N, (shown in Fig. 5,) secured to a bracket 12, is adapted to keep the surface of the pressingu'oller clean, so as to avoid the accidental application of any glue to the outer sides of the flaps.

A carton is shown in Fig. 3 at X, being represented as filled in this case, and the flaps to which the glue is to be applied are shown at a: 00 between the pressing-rollers and the faces of the gluing-wheel.

The glue-pot is shown at Y and supplies the needed glue to the side faces of the wheel member, as is fully set forth in my prior applications hereinbefore mentioned.

I consider my invention independent of the details of construction, inasmuch as the same may be varied considerably without materially affecting the operation.

I claim as new and desire to secure by Letters Patent-- 1. In a gluing-machine,agluing-wheel having a side face adapted to apply the glue, said gluing-wheel being composed of a plurality of sections geared to rotate at different speeds whereby the facial velocity of the glue-applying portions may be substantially the same; substantially as described.

2. In a gluing-machine,agluing-wheel having a side face adapted to spread the glue,said wheel being composed of a plurality of sections of different diameters geared together to rotate at different speeds and making up a practically continuous gluing face, the parts of which move at approximately the same facial speed; substantially as described.

3. A gluing-wheel composed of an outer peripheral section, E, and an inner section, F, concentric therewith, said sections being held together and adapted to rotate at different speeds; substantially as described.

at. In a gluing-Wheel, the combination of the outer section, E, carrying the gear, 6 the inner section, F, carrying the rack, f, and the pinion, 0, between which and the rack, the gear, 9, rotates; substantially as described.

In witness whereof I have hereunto set my hand, at Rockford, in the county of Winnebago and State of Illinois, this 14th day of August, A. D. 1901.

CHARLIE REDD.
